Automated Analysis for the Chemical industry

Yes, titration can be fully automated in a chemical laboratory, from sample weighing and dissolution through to the titration itself and result reporting. Alsys lab robots run titration, including heated titration, as part of an unattended sample preparation and analysis workflow, integrated with titrator instruments such as those from Metrohm and Mettler Toledo.

Automating titration removes the largest source of manual variation in oleochemical QC: weighing, dissolving, and dosing titrant by hand. The robot executes each step to identical tolerances every time, which is what makes titration results comparable across shifts and across analysts.

Automated acid value analysis runs unattended from sample loading to result: the robot weighs the fat or oil sample, dissolves it in the appropriate solvent, and titrates it against a standardized base, with the endpoint and result transferred directly to LIMS or SAP against the sample identity.

Because acid value is sensitive to weighing precision and consistent titration speed, automation typically improves repeatability over manual analysis. The specific method and titrant used are configured to match the laboratory’s existing standard.

Automated saponification value analysis runs the reflux, dilution and back-titration sequence unattended: the robot weighs the sample, adds the alcoholic potassium hydroxide reagent, manages the heated reaction step, and back-titrates the excess base, reporting the result directly into LIMS or SAP.

The heated reaction step is where manual saponification analysis loses the most time and consistency, since reflux duration and cooling before titration are easy to vary by hand. Running the full sequence on a fixed timer removes that variation.

Yes, iodine value determination can be automated, covering sample weighing, reagent addition, the halogenation reaction, and back-titration of the unreacted reagent, with the result reported automatically against the sample identity. The robot manages reaction timing and titration precisely and consistently across every sample.

Because iodine value reflects the degree of unsaturation in a fat or oil, consistent reaction timing across samples is important for comparable results; automation removes the analyst-to-analyst variation that a manually timed halogenation step introduces.

Automated hydroxyl value analysis runs the acetylation reaction and subsequent titration unattended: the robot weighs the sample, adds the acetylating reagent, manages the reaction step, and titrates the result, reporting the hydroxyl value directly to LIMS or SAP.

Hydroxyl value is one of the more time-consuming oleochemical parameters to run manually, since it depends on a controlled reaction step before titration. Running it unattended allows it to be scheduled overnight or alongside other analyses without occupying an analyst.

Yes, peroxide value analysis can be automated, including sample weighing, dissolution, reagent addition, and titration of the liberated iodine, with the result transferred directly into LIMS or SAP. Because peroxide value indicates oxidation and can change during handling, running the method on a fixed, repeatable schedule improves the comparability of results between samples.

Automation is particularly relevant for peroxide value because manual handling time before titration can itself affect the result; the robot executes each sample identically, removing that variability.

Carbonyl and bromine values are analyzed within the same automated framework as other oleochemical titrations: the robot weighs the sample, prepares it according to the configured method, and carries out the titration or colorimetric determination, reporting the result against the sample identity directly to LIMS or SAP.

Daily capacity in a chemical plant laboratory depends on which parameters are configured, since a straightforward titration takes far less time than a heated reaction such as saponification or hydroxyl value. Because the system runs unattended around the clock, daily throughput is set by method cycle time rather than by staffing.

Time to first result depends on the method: a straightforward titration such as acid value can return a result within roughly an hour of loading, while methods with a reaction or heating step, such as saponification or hydroxyl value, take longer to complete the reaction stage before titration.

Because the robot starts preparation immediately on loading rather than waiting for an analyst to become available, the wait before a sample enters the workflow is removed even where the chemistry itself takes time.

Heated titration is a titration method that requires the sample to be heated, refluxed, or maintained at a controlled temperature before or during titration, as used in determinations such as saponification value. Yes, heated titration can be automated: Alsys robots manage the heating step, reaction timing and subsequent titration as a single unattended sequence.

Heated titration is one of the more difficult methods to run consistently by hand, since reaction temperature and duration both affect the result. Automating the heating step is what makes the method reproducible from sample to sample.

Automated liquid dosing and dilution in an Alsys system uses closed-loop, verified volumes: the robot doses reagents and solvents to the exact quantity a method specifies, dilutes samples to a defined volume, and records each dosing step against the sample identity, removing the margin an analyst might add by hand.

Closed-loop dosing also protects analysts from direct contact with corrosive reagents and solvents, since the reagent is measured and transferred inside the enclosed workflow rather than handled manually at the bench.

Lab automation handles hazardous chemical sample preparation inside a fully enclosed workflow, so analysts are not in direct contact with corrosive acids, alkalis or solvents during weighing, dosing, heating or titration. The robot performs each step to the same protocol every time, which also removes the risk of a rushed or improvised step under time pressure.

For chemical and oleochemical analysis, Alsys integrates titrators and related analytical instruments from Metrohm, Mettler Toledo, Thermo Fisher, Shimadzu, Agilent, Avantes and Sartorius, mounted inside the robot enclosure or positioned alongside it depending on the method and footprint. Existing laboratory instruments can usually be integrated rather than replaced.

Where a specific instrument is not already supported, integration is developed by the Alsys software team, so the choice of analyzer is generally driven by the customer’s method rather than by what the robot can accept.
